All right, so it's not Steve Jobs pulling a phone out of his pants pocket, I'll grant you. But for owners of the early 2009 Mac Pro models running Snow Leopard, the 1.64MB firmware update is probably a welcome release.

According to Apple's release notes, the update is aimed at Mac Pro models from early 2009—those are the ones released last March—running Mac OS X 10.6.2. The update reduces processor utilization during audio activities such as playing or recording music.
